Letters Patent No. 78,998, (lated June 16, 1868.

IMPRQVEMENT IN COMBINED HARRQW, DRILL, PLANTBB., AND ROLLER.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, DAVID B. PLATT, of Madison, in the county of Jefferson, and State of Indiana, have invented a nier.y and improved Combined Harrow, Drill, Planter', and Roller; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying` drawings, forming part of thisspcoification, and in whieh Figure 1 is a top-or plan view of my improved machine.

Figure 2 i's'a vertical longitudinal section ofthe same, taken through the line a: x, fig. 1..

Figure'S is a vertical cross-scction cf the same, taken through the line w ze, iig. 1. y

Figure d is a detail longitudinal sectional view ofthe seed-box and dropping-device for lplanting.

Figure 5 is a detail cross-section et" the same, taken through the line y y, fig. L1.

Figure G is a. detail cross-section ofthe saine, taken through the line a e, fig. e.

Similar letters of reference indicate corresponding parts.A

My invention has for its object to furnish an improved combined barrow, drill, planter, and roller, so constructed and arranged that the drill and roller or planter and roller may be used togetheig'or the roller and harrow may cach be used alone, as may be desired, according to the particular work to be done.

And it consists in the construction, combination` and arrangement of the variouspxirts ofthe machine, as -ivill be hereinafter more fully described. u l

A is the frame of the machine, to the forward cross-bar of which the ploivs or markers B are attached, by which the ground is opened to receive theseed. 4

The rear parts of the plows or markers B are divided, as shown in fig. 3, so that the seed maybe introduced into the bottom oF the marks or furroivs opened by the piows, and be covered by the iniiow of the soil in the rear of the said pions.

The standards ot' the plotvs B arc adjnstably secured to the said cross-bar, so that they may bc set higher or lower, as may be desired.

C is the drill seed-box, which rest-s upon the frame A, and is removably secured' in place by the'hooks D.

E is the droppingshaft, which revolves in bearings attached to the scedbox C, and which receives motion from the wheels F, attached to its ends, and which roll alongrthe ground.

The shaft E is grooved, or has grooved wheels attached to it, as shown in figs. l, 2, and 3, and in. the bot toms of said grooves are formed holes or recesses, to receive the seed and carry it out of the seed-box, said recesses being of such a size as to hold the quantity of grain required to be dropped at cach time.

G are adjustable gauges, attached to the front side of .the box O, toregulate the escape of the seed. H are stationary plates or tongues, attached to the rear side or bottom of thc box C to prevent the rearward escape of the seed throughthe grooves of the shaft E.

I is the roller, which is made in two parte, as shown in tlg. 1, and is removably pivoted to the frame A by the rod J, which passes longitudinaily through the centres of said rollers, and through the longitudinal bars of the frame A.

K1 K2 Ka are cross-bars, secured to the frame A, and having long downwardly-projecting teeth attached to them. The bars K1 K3 may be permanently attached to the frame A, but the bar K; can only,r be used. when the rol-ler I is removed.

L is the tongue, which ispivotcd to the middle part ofthe front cross-har ofthe frame A.

M is a bar or arm, the forward end of which is rigidly attached to the tongue L, and 'which passes 'back beneath the shaft E, and to its roer end is pivotcd the lower end ot the connecting-rod N, which passes up through a slot in the centra-l longitudinal bar of the frame A, and its upper end is pivoted to the forward end ofthe lever O. A i

The lever O is -pivotcd to the standard I by a pin, passing through the said lever, and through one or the other of the several holes formed through the said standard, so that the said lever may be raised or lowered, as

desired,

When the forward end of the tongue L is fast in the neck-yoke of the horses, by lowering the rear'end of lthe lever O, the forward end of the frame A will be raised, raising the plo-ws B away from the' ground, and by operating the said lever O, the 4plous or markers B may beadjusted to run at any desired depth in the ground. rlhe rear end of the lever Q is secured in place when adjusted by a pin,passing through the said lever, and through one or the other of the several holes formed in the standard Rfor its reception. f

S is' the planter seed-box, which when inv use, is secured to the forward part of the frame A by hooks, in the same manner and in the same place as the drill seed-box C.

T is a shaft, which works in bearings attached to thebottom ofthe bei; S.

To the ends of the shaft T are attached the dropping-cylinders U, which communicate with the interior of the seed-box S through slots formed in the bottom of said box,'and which have holes or recesses formed in their opposite sides, to receive the seed from the box S, and drop it to the ground. I

Vare rubber or other elastic plates or Scrapers, attached to the bottom of the'seedbox to prevent any more than the desiredquantity of seed from passing out.

To the shaft-T is attached a small gear`or pinion-wheel", W, into the teeth of which meshlthe teeth of the v curved rack or segment X, formed upon or atta-:hed to the lower end of the lever Y.

The leverYpasses up through a small compartment formed in the middle part of the seed-box S, is pivoted tothe upwardly-projecting part of one ofthe partitions that form the said compartment, and its upper end projects suihciently to allow it to be grasped and conveniently operated by the driver to-drop the seed.

By removingr the seed-box and rollers, and securing ,the toothed bar Kz in place, asshown in red'in g. 2, the machine becomes simply a barrow. By removing the toothed barA K2, and attaching the rollers I, the machine becomes simply a roller. By attaching the drill seed-box C to the frame A, themaehine becomes a. combined drill yand roller; and by removing the drill seed-box C, and attaching the planter seed-box S, the machine -becomesacombined planter and roller.

These adjustments are all easilyI and quickly made, making thel machine veryconvcnient arid elective for farmers use. l

I claim as new, and desire to secure by Letters Patent- 1: The combination of the rollers I with the removable seed-box C, drill-shaft E,whecls F, adjustable plows P, nnd'i'rame A, allvconstructed, arranged, and operating substantially as described.

@The combination of the removable seed-box S, shaft T, planting-rollers U, pinion W, toothed rack4 S, and lever Y, with the adjustable plows B and frame A, all constructed, arranged, and operating substantially as set forth. 4

S. .The combination ofthe pivoted'tong'ue L,- bar M, connecting-rod N, pivoted lever O, perforated standards I R, and frame A, substantially as described, and for the purpose specified.

4. The combination of the slides G, plates H, removable seed-box VC, roller E, and wheels F, substantially as described.

5. The frame K, when its` front and rear cross-bars, Kl K5, are provided with teeth,-in combination with the removable toothed cross-bar K2, substantially as set forth.
